Scintillators are vital components in high-energy radiation detectors and are used in fields like high-energy physics, non-destructive testing, radiochemistry, and medical diagnostics. Scintillators with aggregation-induced emission (AIE), through rational molecular design and preparation techniques, can be endowed with such properties that effectively overcome the inherent defects of existing inorganic and/or organic scintillators, such as high costs and poor mechanical properties in inorganic types and low light yield and aggregation-caused quenching for organic kinds, thus affording novel optoelectronic properties, superior performance, and broader applications. This review classifies AIE scintillators from a molecular perspective, based on their luminescence mechanisms and construction strategies, into fluorescent scintillators, thermally activated delayed fluorescence scintillators, metal cluster scintillators, organic-inorganic hybrid scintillators, and metal-organic framework scintillators. This review starts with analyses of these building strategies and the structure-performance relationships and then describes the applications of AIE scintillators based on their molecular structures and optoelectronic properties.

具有聚集诱导发射的闪烁体


闪烁体是高能辐射探测器的重要组成部分，用于高能物理、无损检测、放射化学和医学诊断等领域。具有聚集诱导发射 （AIE） 的闪烁体，通过合理的分子设计和制备技术，可以赋予其特性，有效克服现有无机和/或有机闪烁体的固有缺陷，例如无机类型的高成本和较差的机械性能以及有机类型的低光产率和聚集引起的猝灭，从而提供新颖的光电性能， 卓越的性能和更广泛的应用。本文根据 AIE 闪烁体的发光机制和构建策略，从分子角度将 AIE 闪烁体分为荧光闪烁体、热激活延迟荧光闪烁体、金属丛集闪烁体、有机-无机混合闪烁体和金属-有机框架闪烁体。本文首先分析了这些构建策略和结构-性能关系，然后根据 AIE 闪烁体的分子结构和光电特性描述了 AIE 闪烁体的应用。
